I just had the clutch of my 2001 Marea 1.6 Weekend changed, ever since then, it is been raving intermittently when hot. Runs fine when cold. When at resting position it raves continuously on its own and when not raving persistently the rave is up to 1500. Guy what do you think is wrong here?

I'm tempted to say it's a crankcase breather pipe. But I'm sure one of the more technically minded guys will have a better idea.

sounds like a vacuum leak. you need ot check all the pipework on the intake carefully. a vacuum pipe may have been knocked or cracked by the mechanics during the clutch replacement.
